While many golfers focus on shoulder turn or hip rotation, Jason demonstrates that proper hand placement is crucial for hitting straighter, more consistent shots.

In this webinar recap, we’ll explore:

1. Screening & Measurements (How Jason evaluates each student’s wrist mobility, grip strength, and hand size)
2. Common Grip Categories (Weak, Neutral, Strong – why each matters for ball flight)
3. Using HackMotion to Fix & Fine-Tune (Data-driven insights for shaping a grip that supports a stable clubface)

Grip Screening and Measurements

Before any technical changes, Jason conducts a quick but thorough evaluation of a golfer’s grip to fully understand their range of motion and how that impacts their ability throughout the golf swing.

Physical capabilities will play into the wrist action you can take in your golf swing.

Wrist Range of Motion

• Extension & Flexion: Can the student flex their lead wrist enough to close the clubface, or are they stuck in extension?
• Radial & Ulnar Deviation: Does the student have enough ability to hinge (radial) and unhinge (ulnar) without strain?

Forearm Rotation

• Pronation & Supination: Jason checks how much the student can rotate their forearm. Limited pronation/supination can affect how they square the face.

Grip Strength Test

• Using a hand dynamometer, Jason measures a golfer’s grip strength. If players lack grip strength, a stronger grip placement with the club more in the fingers will help square the face without excessive wrist action.

Hand Size & Grip Size

• Small Hands: Often force the handle up into the palm, limiting wrist mobility. These players typically need thinner grips to wrap more fingers around the club and create more mobility in their hands.
• Large Hands: Can more easily adopt a stronger, finger-based hold. They may benefit from thicker grips if they’re over-rotating (hooking).

Weak, Neutral, and Strong Grip Categories

Once Jason determines a student’s physical profile, he classifies their grip as weak, neutral, or strong. Each category has distinct effects on wrist mechanics and clubface control.

Weak Grip

• Characteristics: The club sits high in the palm with fewer knuckles visible on the lead hand.
• Typical Miss: Tends to open the face (slice).
• Why It’s Tricky: There is a limited range of motion in the wrists, making it tough to square the club at impact without extreme manipulation.

Neutral Grip

• Characteristics: The club crosses the lifeline from the base of the pinky to the index finger; 1–2 knuckles are visible.
• Ideal For: Balanced wrist hinge and easier movement into flexion/extension.
• Consistency: One of the best grips for helping golfers create a repeatable release position.

Strong Grip

• Characteristics: More knuckles are visible on the lead hand, and the handle sits deeper in the fingers.
• Benefits: It makes it easier to move into flexion in transition (closing the face sooner), reducing slices.
• Caution: Overdoing it can lead to hooks or pulls if combined with poor face/path control.

Using HackMotion to Fix Grip Issues

Once a student’s grip is established, the HackMotion can provide real-time feedback on wrist angles and grip consistency.

Most importantly, small grip tweaks can be analyzed using the data from HackMotion on extension and flexion numbers. This process eliminates guesswork and improves the learning process.

Real-World Example: Jessica’s Setup Fix

In this webinar, Jason also goes through the process he did with Jessica a top student of his who was struggling with a weak grip that caused too much extension in the lead wrist at impact. She was measuring nearly 22 degrees of extension at impact.

Jason made the following adjustments:

• Stronger Grip – Moved the club more into the fingers, showing 2+ knuckles.
• Ball Position – Shifted it slightly back, ensuring the handle wasn’t lagging behind.
• Slight Forward Shaft Lean – Helped reduce extension at address.

The results showed that Jessica moved to about 8 degrees of extension at impact, and she noticed a straighter shot and better overall compression.

Final Thoughts

From TPI-style screenings to HackMotion data, Jason Birnbaum shows how a well-fitted grip sets the stage for proper wrist mechanics.

It’s important to remember that the physical characteristics of golfers will determine some of their ability when it comes to wrist action in the golf swing.

Despite her strong overall game, she found herself battling a laid-off club position in her backswing, leading to an open clubface and a last-second flip at impact.

In this exclusive webinar, Dan demonstrates how HackMotion was used to analyze and correct her wrist angles, helping her achieve a more stable clubface and consistent ball flight—especially under tournament pressure.

Watch the full webinar recording below.

Identifying the Problem

Dan saw that the club was laid off in the backswing. However, on the downswing, instead of fixing this position, Sadie shallowed the club even more, something unusual among better players.

Here are the issues he spotted in her swing.

Laid-Off Club Position

• As Sadie reached the top of her backswing, the club became significantly laid off, meaning it pointed too far to the left of her target (for a right-handed player).
• The issue worsened on the downswing, causing the shaft to move behind her hand path and leaving the clubface open.

Trail Wrist & Forearm Rotation

• Her trail wrist was transitioning from a radial (cocked) position into ulnar (uncocked) too early.
• Simultaneously, her trail forearm began to pronate, and her trail wrist started moving into flexion, which made the laid-off position much worse.
• These movements forced a rapid, exaggerated, last-moment rotation of the clubface at impact, causing inconsistency and often resulting in a strong over-draw.

Using HackMotion to Diagnose & Fix Swing Issues

To confirm the specific wrist and forearm movements causing Sadie’s issues, Dan Whittaker used HackMotion. While he had a general sense of the issue, he wanted to measure it in real time to develop a plan that would help Sadie.

By analyzing the data, they pinpointed the precise moments when Sadie’s wrist angles began to deviate and how that led to the laid-off club position.

With the problem identified, it was time to consider what could be done to fix it. It was off-season for Sadie, so she had some time to work through a fix.

Awareness and Measurement

• Sadie wore the HackMotion sensor during practice to monitor her trail wrist angles.
• The data revealed exactly when her wrist started moving from radial to ulnar and pronating excessively, helping her coach design targeted drills.

Technical Drills

• Halfway-Back Drill: Sadie practiced swinging only to the halfway-back position, then rotating fully to the top without letting the shaft lay off further.
• Wrist Stability Training Aid: She wore a training aid on the back of her trail wrist to maintain a more stable angle (avoiding early ulnar deviation) and ensure the trail wrist did not move toward flexion at the top of the backswing.
• Forearm Rotation Control: Emphasis was placed on preventing excessive pronation at the top to keep the shaft in a better position.

Continuous Feedback

• After each drill, Sadie and her coach checked the HackMotion readings to verify improvement and ensure the fix was transferring to her full swing.
• Gradual progress was made in reducing the laid-off position and limiting the need for last-second face rotation through impact.

Did It Work?

After spending some time working on these fixes, here are the changes that Sadie and her coach have seen.

• Sadie’s ball flight progressed from a massive over-draw to a more controlled, slight cut.
• She reported feeling more energy and consistency in her strikes thanks to improved wrist and forearm positioning.
• The improved wrist angles helped with accuracy and allowed her to generate better ground reaction forces, enhancing her overall swing efficiency.
• With her wrist motion now in a more stable position, Sadie can refine other areas of her swing to improve both power and consistency.

Final Thoughts

Even elite young players like Sadie Adams can face significant issues with wrist angles and club positioning.

By using HackMotion to identify and quantify the problem and implementing well-designed drills—supported by consistent sensor feedback and a training aid—Sadie and Dan Whittaker successfully moved away from the laid-off club position and excessive face rotation through impact.

She now has a more stable and powerful swing, setting her up for better results in 2025.

Adam explains the laws and how you can make changes and adjustments in your swing to always have a square face at impact. If you don’t have time to watch the entire video, here is a brief recap of all the most important information.

Key Takeaways

• Aim for a ball first, turf second strike to improve overall shot quality.
• Experiment with different grip strengths and adjust wrist angles for desired face orientation.
• Modify the hand path to influence the club’s swing path, and practice both inside out and outside in paths.
• Focus on synchronizing body rotation with arm movements to develop a smoother and more controlled swing path.
• To generate more speed, extend the hand path.

Impact Laws and Wrist Angles

Here’s a brief overview of the impact laws and how wrist angles play into the angle of the face at impact.

Face Strike

To improve sweet spot strikes, golfers need to adjust both their hand path and club orientation. Practicing with different hand positions at impact to understand how the face is controlled by the wrists.

To get to the proper position at impact, you’ll need to understand what the clubface looks like at impact.

Ground Contact

You’ll need a ball first and turf second strike to achieve consistent ball striking. To get the best ground contact position, you will want to adjust the swing low point.

To get a consistent low point in the swing, work on drills to stabilize the hand position relative to the ball at impact. Unnecessary hand and wrist movements will lead to inconsistent and poor strikes.

Face Direction

Having a neutral grip at impact will lead to your best chance of success throughout the golf swing. Work on flexion and extension exercises to learn to control the face orientation. In addition, play with the effects of a strong and weak grip on the face direction at impact.

Club Path

Golfers should understand how to take an inside-out and outside swing path. If you can feel different swing paths, you can fix errors quickly on the course and get back to a square ball strike.

Body rotation and arm swing need to be synchronized to make proper adjustments to the club path.

Club Speed

The larger the swing and the longer the hand path, the more speed you can get from the golf club. Combining body rotation and wrist hinge (not one without the other) will help to efficiently transfer power.

Acceleration drills are recommended to ensure you are always moving the club through impact at a high rate of speed.

Angle of Attack

To improve the angle of attack, work on the release of the timing. In addition, the swing plane can be adjusted to find the most effective angle based on the club in the hand.

Finally, all golfers should know the ball position and weight distribution and how that plays into the angle of attract and ground contact.

Dynamic Loft

Dynamic loft can be adjusted with shaft lean at setup and again at impact. When going for a golf club fitting, optimize dynamic loft for your individual swing characteristics. Wrist angles at impact can be adjusted to control the loft.

Final Thoughts

The wrists and hands have a tremendous impact on ball flight. By breaking down these impact laws and how wrist angles play into them, we can learn a lot about improving the direction, accuracy, and distance of all golf shots.

Take some time to watch this video, and do it while you wear your HackMotion. See where your game could use a little help to become a more consistent ball striker.

Key Takeaways

• At setup, with a neutral grip, the ideal wrist position extension range should be between 10 and 25 degrees. Less extension would indicate a weak grip, while more would be strong.
• More important than grip position is grip strength consistency; using a neutral grip more often than not is best.
• At impact, the goal is to be 15 to 30 degrees more flexed than at the start; without this movement, flipping becomes a problem.
• Focus on the 9 to 3 drill (halfway back to halfway through) to determine the root cause of your wrist issues at impact.
• Being too extended at the top of the swing should be avoided; look for +5 to -10 degrees from the setup position.
• Problems in the takeaway, like adding extension as the first move, an early hinge, or an upper body sway, will lead to poor wrist action and more inconsistency in the golf swing.

Wrist Position Goals at Setup

If you aren’t putting yourself in a good position to start your swing, it becomes very difficult to get your golf game to the next level.

Tyler brings up an interesting point about ensuring that the amount of grip extension is not the only thing we focus on at setup. In addition, you’ll need to look at how your grip matches your sternum or body position.

Grip strength consistency can be tested with the HackMotion. Go through a practice session and pay close attention to the starting position of the lead wrist. Is it changing often?

Proper Impact Position for Consistent Ball Striking

The goal is to be 15 to 30 degrees more flexed at impact than you are at the start of your golf swing. Many golfers who struggle to get to the proper position at impact tend to have too much extension at setup.

This leads to a flip, which is usually caused by getting into a flexed position and then losing it (usually because of poor body rotation or movement) and never getting enough flexion, sometimes from too much grip pressure.

Test to See where Your Wrist Issues are

Tyler mentions a great test to see why your wrist may not be in the correct position at impact.

Take a half swing from 9 to 3 and see if you are able to square the clubface and get to that flexed lead wrist position. Wear your HackMotion as you see how your wrist action changes from a full swing to this half swing.

• If you can do it on the halfswing, you know your backswing is the issue.
• If you can’t do it, your brain just doesn’t know how to deliver the club in the proper position just yet (you’ll need to work on release training and hitting more with your body and less with your hands).

Spatula Drill for Face Direction

If you need a better visual of what your golf club face should look like through impact, you can use a spatula. Hold a spatula like a golf club, and adjust grip strength and wrist position (flexion/extension) to simulate changes in the club’s face.

This is done to help understand the relationship between grip, wrist action, and clubface direction. If you can learn how to do it with a spatula, move to the golf club and see if you have better control over the face orientation.

What will Improve Your Impact Position the Fastest?

Tyler talks about the different things you can work on in your golf game to start to improve the impact position. One of the most important things to work on is body movement, and especially the takeaway.

The goal at the top of the backswing is to ensure you are within range of where you were at setup. This usually means you are swinging with the body and pivoting correctly.

In addition, pay close attention to take away problems known to lead to poor wrist action. Using arms too much, adding extension as the first move, an early hinge, and too much flexion too soon will all be the root causes of these issues.

Final Thoughts

Take a look at the entire webinar from Tyler and go through some of the Q&A to see if there is a particular question or player profile that relates to your swing.

The great thing about the data that HackMotion can collect for us is that it’s actionable and something that you can continue to work on at your own pace.
